چکیده

Nucleation and subsequent growth of particles was studied in the CLOUD7 chamber experiment at Cern. Experiments were performed in varying concentrations of sulphuric acid, ammonia, dimethylamine and α-pinene, and using both ozone and hydroxyl radicals as oxidizers. Particle growth rates were determined at size ranges <1.5 nm, 1.5–3 nm, and >3nm. Comparison of the growth to the amount oxidized organics in the mass range 300–450 amu was made.

The role of low volatile organics on secondary organic aerosol formation

Large-scale atmospheric models, which typically describe secondary organic aerosol (SOA) formation based on chamber experiments, tend to systematically underestimate observed organic aerosol burdens. Since SOA constitutes a significant fraction of atmospheric aerosol, this discrepancy translates into an underestimation of SOA contribution to radiative forcing of atmospheric aerosol. Here we sho...

Atmospheric nanoparticles formed from heterogeneous reactions of organics

Atmospheric aerosols directly and indirectly affect the radiative balance of the Earth’s atmosphere1. Nanoparticles are a key component of atmospheric aerosols, growing rapidly under ambient conditions2–4. Organic species are thought to lead to the growth of nanoparticles smaller than 20 nm (refs 5, 6), but the identity of these species and the underlying chemical mechanisms remain elusive. Her...

Molecular understanding of atmospheric particle formation from sulfuric acid and large oxidized organic molecules.

Atmospheric aerosols formed by nucleation of vapors affect radiative forcing and therefore climate. However, the underlying mechanisms of nucleation remain unclear, particularly the involvement of organic compounds. Here, we present high-resolution mass spectra of ion clusters observed during new particle formation experiments performed at the Cosmics Leaving Outdoor Droplets chamber at the Eur...

Reply to Liu et al.: On the importance of US deposition of nitrogen dioxide, coarse particle nitrate, and organic nitrogen.

In PNAS (1), we highlight changes in the balance of oxidized and reduced nitrogen contributions to US reactive nitrogen (N) deposition. Successful reductions in nitrogen oxides (NOx) emissions combined with modest growth in ammonia emissions have now tipped the balance in most regions toward deposition of reduced N species, ammonia and ammonium. Liu et al. (2) respond, making two main points. F...

Prediction of the pharmaceutical solubility in water and organic solvents via different soft computing models

Solubility data of solid in aqueous and different organic solvents are very important physicochemical properties considered in the design of the industrial processes and the theoretical studies. In this study, experimental solubility data of 666 pharmaceutical compounds in water and 712 pharmaceutical compounds in organic solvents were collected from different sources. Three different artificia...
